Subscriber Captcha Code Entry

This modification will add another layer of security to your subscriber pages in the form of a Captcha image. A random set of easily read characters is generated each time the page is refreshed which are required before hitting the Submit button. This will identify whever you are human or a malicious piece of code running on another computer and should prevent spam bots from clogging your news with invalid eMail addresses. Which may result in your mail server being blacklisted.

Changing the button styling was quite easy as was adding new CSS Classes and removing the default font styling in order to display the @font-face fonts chosen for the site.

The Captcha can be toggled off and on from within the config.php file as with other phpList features.

Another bonus with this is that everything is contained within your system and you are not required to sign up for a third party account in order to obtain recaptcha keys (private and public).

Shown below are all the code modifications required to add Captcha Security to the subscriber page.
